2002 Dodge Caravan

Do you mean the pointer is on the wrong side of the stop at "0"? Drive fast enough that the pointer would be more than half scale. When the computer positions the pointer correctly, you're done.

If that doesn't work, the dealer can connect their DRB3 scanner and run all the gauges through their range then bring them all back down to "0". The third way is to pull the lens off the instrument cluster and push the pointer counter-clockwise back to zero.
